Thermal analysis is a valuable tool in diagnosis of wiredrawing lubricant problems. It allows the formulator to examine the physical properties of the lubricant under thermal conditions present in the wire/die interface. The data can be used to develop new lubricants when there is a solid understanding of thermal issues in the drawing operation. Thermomechanical analysis is a required companion to differential scanning calorimetry. It allows exploration of the mechanical effects of melting and allows the lubricant formulator to better predict lubricant behavior in the wiredrawing operation. The future of lubricant development will hinge on understanding the thermal issues in wiredrawing. New lubricant technologies and chemistries can be examined at the bench with these methods prior to going to trial in the wire mill.
